Abstract

The invention discloses a lime soil storage method for soil test. The lime soil storage method comprises the steps of firstly opening a curing box and placing lime soil onto a separating plate; then,adding citric acid into a first sealed chamber of a carbon-dioxide generator, and adding sodium bicarbonate to a second sealed chamber of the carbon-dioxide generator; then, extending one end of a first tube into the citric acid from a first liquid outlet in the first sealed chamber, and extending the other end of a second tube into a second liquid outlet in the second sealed chamber; then communicating an air outlet in the second sealed chamber with a curing chamber in the curing box through the second tube, and finally opening a control valve on the second tube; and finishing the arrangementof a lime soil storage environment. The invention further discloses a device for achieving the lime soil storage method for soil test, and the problem of poor storage conditions during test of a limesoil sample is solved.

Description

technical field [0001] The invention belongs to the technical field of storage equipment, and in particular relates to a method for storing lime soil for geotechnical tests, and also relates to a storage device for lime soil for geotechnical tests. Background technique [0002] In the field of geotechnical engineering, different kinds of rock and soil masses are often encountered, which have more or less different engineering problems. For example, the distribution area of ​​subsidence loess accounts for about 60% of the loess area in my country, and it is a regional soil widely distributed in my country. The structure of this kind of soil will be destroyed after being soaked in water. Significant additional deformation is prone to occur under the combined action, leading to serious engineering problems; permafrost refers to various rocks and soils below zero degrees Celsius and contains ice. It is a soil medium that is extremely sensitive to temperature and is mostly distrib...
